A lenticular cloud covers the summit crater of Mayon Volcano, Philippines.. As air travels along the surface of the Earth, obstructions are often encountered, including natural features, such as mountains or hills, and artificial structures, such as buildings and other constructions, which disrupt the flow of air into "eddies", or areas of turbulence.
Cloud chart showing major tropospheric cloud types identified by standard two-letter abbreviations and grouped by altitude and form. See table below for full names and classification. The table that follows is very broad in scope much like the cloud genera template near the bottom of the article and upon which this table is partly based.
Stratus silvagenitus is a type of stratus cloud.The word silvagenitus is a scientific Latin coinage meaning "created from forest". [1] This cloud type forms over forested areas which are experiencing high relative humidity levels, for example, after precipitation has passed, through evaporation and/or evapotranspiration.
A curious cloud photographed over Smith Mountain in Virginia this week looks more like something out of a fairytale or painting than it does in real life — and the science behind the formation ...
A cap cloud is a special form of the lenticular cloud with a base low enough that it forms around and covers the peak, capping it. [3] A chinook arch cloud is an extensive wave cloud. It has this special name in North America where it is associated with the Chinook wind. It forms above the mountain range, usually at the beginning of a chinook ...
Clouds of the lenticularis species tend to have lens-like shapes tapered at the ends. They are most commonly seen as orographic mountain-wave clouds, but can occur anywhere in the troposphere where there is strong wind shear combined with sufficient airmass stability to maintain a generally flat cloud structure. These two species can be found ...
Its base is near the height of the mountain peak, though the top can extend well above the peak and can merge with the lenticular clouds above. Rotor clouds have ragged leeward edges and are dangerously turbulent. [4] A foehn wall cloud may exist at the lee side of the mountains, however this is not a reliable indication of the presence of lee ...
